/Engine/Source/Runtime/PreLoadScreen/Public/PreLoadScreen.h
Interface that defines the class that handles all the logic for controlling / displaying a particular PreLoadScreen. Designed to be implemented in a Plugin that callsFPreLoadScreenManager::RegisterPreLoadScreenso that functions are called by PreLoadScreenManager correctly. Really should probably inherit fromFPreLoadScreenBaseinstead of this class for more functionality
